SASH-FASTENER.

Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed October 10, 1910. Serial No. 586,340.

To allwhom it may concern:

Be it known that I, REGINALD WARE, a citizen of the United States,residing at Lewiston, in the county of Androscoggin and State of Maine,have invented certain new and useful Improvements in Sash-F asteners;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in sash fasteners.

The invention consists of certain novel features of construction,combination and arrangement of parts as will be more fully described andparticularly pointed out in the appended claim.

In the accompanying drawings: Figurel is a vertical sectional viewthrough the meeting edges of the two rails showing the application ofthe invention. Fig. 2 is a plan view of the same. Fig. 3 is a verticallongitudinal view of the fastener showing the parts in lockedengagement. Fig. 4 is a perspective view of the spring projected lockingbolt of the device. Fig. 5 is a similar view of the keeper or boltengaging member of the device. Fig. 6 is a vertical cross sectional viewof the device, on the line 6-6 of Fig. 3.

My improved sash fastener comprises a bolt member 1 and a keeper member2 either of which may be secured to the upper or the lower sash. Thebolt member comprises a base plate 3 having on its opposite side edgesupwardly projecting anges 4 in which are formed longitudinal guidegrooves or channels 5. On the outer end of the plate 3 is formed anupwardly projecting stop lug 6 the upper end of which is rounded orformed on a curve.

Slidably mounted on the plate 3 is a flat bolt 7 having on its oppositeside edges longitudinal tongues or ribs 8 which are adapted to slidablyengage the guide grooves 5 in the flanges 4 of the base plate. On theouter end of the bolt 7 is formed an upwardly and rearwardly projectingtransversely curved flange 9 which slidably engages the stop lug 6 onthe base plate and together with said lug forms a housing for a boltprojecting spring 10 which is arranged between the lug and the adjacentend of the bolt. The bolt end of the spring is preferably seated in arecess or socket 11 formed in the end of the bolt as shown.

In the base plate 8 is arranged a stop pin 12 the upper end of whichprojects above the plate and engages a short groove or recess 13 formedin the lower side of the bolt, whereby the movement of the bolt by thespring is limited. On the opposite sides of the plate are formedapertured fastening lugs 14 which are adapted to receive fasteningscrews 15 whereby the bolt member of the device is fastened to the sashrail. The keeper member 2 of the device comprises a block 16 having onits opposite sides apertured lugs 17 which are adapted to receivefastening screws 1S whereby said member is secured to the rail of thecompanion sash. The inner side of the block or the side next to theinner end of the bolt member 1 is beveled or formed at an angle as shownat 19 and in said side of the block at the base or lower end of the sameis formed a bolt'receiving notch or recess 20. By forming the block witha beveled or inclined bolt engaging surface, the projecting end of thebolt, when brought into engagement therewith, by the closing of thesashes, will force the bolt back against the pressure of the springuntil the end of the bolt comes opposite to the notch 20 in the blockwhereupon the spring will force the bolt into locking engagement withthe notch.

Having thus described my invention what I claim. is:

A sash fastener comprising two members, one of which comprisesoppositely disposed upwardly projecting guide flanges and a stop pin,and also having at one end an upwardly projecting flange provided with arounded upper end, the other member comprising a flat bolt havingtongues on opposite sides which are adapted to slidably engage saidguide flanges, said bolt having on its outer end an overhangingrearwardly projecting transversely curved flange which slidably engagesthe stop In testimony whereof I have hereunto set lug on the base plate,said base plate and my hand in presence of two subscribing stop lugproviding a housing, a, socket in Witnesses.

the bolt, a spring mounted in the housing REGINALD WARE. and contactingrespectively with the socket Witnesses:

and Stop ange, and a recess in the bolt to EDW. R. PARENT,

engage the stop pin. METHYL I. DECKER.
